Bifurcation Side Branch Stenosis-Ostial LCX Case and Update on China DCB Registry

Video Transcription

Video Summary

The video transcript discusses the treatment of isolated radial syntysis osteosteone stenosis. The Medina classification is used to categorize the severity of bifurcated lesions, with a minimum diameter stenosis of 50% within 5 mm of true donor vessels. The presence of POC lesions is rare but does not increase complexity. For isolated osteosteone lesions, over 80% of the lesions extend into the radial osteoflax, increasing stenting technique complexity. Different stenting techniques are available, including precise positioning of a short stent to cover the lesion or using a larger enzyme balloon for dilation. The transcript then presents a case of a 72-year-old male patient with unstable angina due to severe osteosteone disease. The presentation includes images showing severe disease and mild plaque in the dyslipoma. The speaker describes the stenting technique used for this case. The transcript concludes with a brief introduction to the DCP Bifurcation Trial, a randomized clinical trial comparing different stenting techniques for bifurcation lesions. The trial aims to evaluate the benefits of drug-coated balloons versus conventional balloons in treating side branch lesions. The primary endpoint is one-year MACE. The presenter acknowledges the challenges of designing the trial and the impact of COVID-19 on enrollment. The panel discusses the use of imaging and physiology in evaluating bifurcation lesions. While imaging is recommended for complex cases, its necessity in general bifurcations is still being studied.
